In the form shown in Fig. 10, the Winding shaft D is provided atits upper end with a collar 3 that is adapted to engage or impinge against the end of the upperbearing2 when the shaft is moved longitudinally in one direction. The means employed for effecting shown in Fig. 3. The sleeve F is provided in which said trunnions turn. While with an elongated slot or notch 6 for receiving a pin 7 on the winding shaft, and the ring E is provided with trunnions S, as shown in Figs. 7 and 8, that lit, in notches 9 in the lower end of the sleeveF, said-trunnions 8 being, of such cross-sectional form that when the ring E is turned from its ver tical position shown in Fig. 7 into its horizontal position shownin Fig. 8, said trunnions 8 will exert pressure onthe, abutment 5 and on the sleeveF, and thus force the winding shaft Ddownwardly and the sleeve F upwardly, thereby causing the collar 3 on the winding shaft tobear tightly against one side of the slot in whichit is arranged and also cause the upper end of the sleeve F to bear tightly against the bottom shaft bearh1g2, When the ring is turned from its horizontal position shown in Fig. 8 into its vertical position shown in Fig. 7, the trunnions 8 will cease to exert pressure on the sleeve F and on the abutment 5, thus releasing the winding shaft and permitting it to be turned in its bearings. The ring E not only serves as an actuating device for moving the cooperating friction elements on the winding shaft and on the part inwhich it is mounted into snug engagement with each other, but, in view of the fact that the sleeve F in which the ring E is mounted is con nected to the winding shaft by. a pin .7 that fits in a slotin said sleeve, said ring can be used as a finger piece to rotate the winding shaft either to tighten or slacken the tapes C. After the ring E has been turned into the position shown in Fig. 8 to lock :the winding shaft, said ring will remain in this position, on account of the fact that the trunnions 8 on same are thenwedged tightly between the abutment 5 on thewinding shaft and the inner ends of the slots 9 in the sleeve I prefer to use a means of the character above described for moving the cooperating frict1on elements of the structure into snug engagement with each other, I wish it to be understood that my invention is not limited to a loose leaf binder of the exact construction above described, for various other means could be used for causing the cooperating friction elements of the structure to snugly engage each other. For example, any other suitable form of cam or wedging device could be used formoving the winding shaft longi tudinally of its bearings, and therefore, in Fig. 9 of the drawings I have illustrated a structure in which the means employed to move the winding shaft longitudinally consists of a device E rotatably mounted on the lower end of the winding shaft between the bottom shaft bearing 2 and an abutment 5 on the shaft and provided with a cam 8 that fits in a notch 9 in the bearing 2 when the winding shaft is unlocked. When it is desired to lock the winding shaft it is only necessary to rotate the device E sufliciently to move the cam 8 thereon out of the notch 9?. This rotary movement of the device E results in. an endwise thrust on the winding shaft D, which causes the collar 3 on said shaft to be forced snugly into engagement with the lower side of the slot 4: in which said. collar is arranged, the winding shaft remaining securely locked until the device E is turned in the opposite direction, so as to position the cam 8 thereon in its notch 9. In the structure shown in Fig. 9 the winding shaft is @turned by means of a key (not shown) that is arranged on a non-circular shaped portion 10 on the lower end of the winding shaft. Each of the tapes C is connected to the winding shaft D by means of a wedgeshaped device 11, shown in Fig. 5, that is arranged in a dove-tail shaped notch or recess 12 in the winding shaft. The device 11 is preferably formed from a thin piece of sheet metal. that is bent into substantially U-shape, so that the end of the tape can be introduced between the overlapping portionsof same, as shown in Fig. 4. Thereafter, the portions of said U-shaped membet at the side edges of the tape are bent or deformed in such a way as to securely lock the tape in said member andalso convert said member into a substantially wedgeshaped device that can he slipped into the dove tail-shaped recess 12. To connect the tape to the winding shaftthe tape is partially wrapped around the member 11 to which it is connected, and said member is then slipped into the dove-tailed notch 12 provided for same in the winding shaft, thus causing a portion of the tape to be positioned between the underside of the member 11 and the bottom of the dove-tailed notch in which said member is arranged,

as shown in'Fig. 4. The tape leads fortapes taut and it is more efficient than awardly from the contracted end of the notch means of this construction is, that the tapes can be quickly connectedto or disconnected from the winding shaft. The opposite ends of the tapes C are connected to the flange 1 on the leaf-clamping member A by means of clips 13 arranged over the end portions of the tapes and over the flange 1, shown in Fig. 6, and connected to said flange in any suit-able manner.

My improved loose leaf binder is of such construction that it can be manufactured at a low cost, owing to the fact that it does not comprise springs or toothed members for locking the winding shaft so as to hold the loose leaf binder in which a pawl and ratchet locking mechanism is used for. locking the winding shaft, owing to the fact that the shaft locking means consists of friction elements and a cam that are not subjected to wear when the winding shaft is being turned either to tighten the tapes or to slacken the tapes- Still another desirable feature of my improved binder is that a single element, namely the ring E, is used to turn the winding shaft and alsoto lock said shaft after the tapes have been tightened.

'I'Iaving thus described my invention, what I claim, and desire to secure by Letters Patent, is: v
